摘要： Systems and methods for synchronizing the playback of streamed content on multiple playback devices is disclosed. The systems and methods include receiving time information based on a network time source in the playback devices connected to a defined network. The playback clock in each playback device is set based upon the time information. A first playback device then generates presentation time information including a start time for playback and broadcast the presentation time information to the other playback device over the defined network. The playback devices use the presentation time information to adjust the presentation time stamps of the frames of the media content in the stream.

摘要： In a recording medium on which is recorded a multiplexed stream including a plurality of first packets (V_main) constituting a first I-picture in a first video stream and a plurality of second packets (V_sub) constituting a second I-picture in a second video stream, information for identifying the first I-picture and information for identifying the second I-picture are recorded on the medium. A recording medium can thereby be obtained that enables the rapid detection, from a small amount of information, of a particular picture included in a stream such as a TS in which multiple content streams are multiplexed.

摘要： Disclosed are various embodiments for facilitating uninterrupted playback of video streams using lower quality cached files. A video file corresponding to an entirety of a video content feature encoded at a first quality may be obtained from another client on a local network. A video stream corresponding to the video content feature encoded at a second quality higher than the first quality is then obtained. The video stream is rendered for playback on a display. In response to detecting an unavailability of the video stream at a particular time in the video content feature, the video file is rendered for playback on the display in place of the video stream and commences at the particular time in the video content feature. The video file may then be sent to yet another client on the local network.

摘要： Disclosed is a method and device for accelerating playback of a single-fragment video. The method includes: when a video playback request sent by a playback end being intercepted, obtaining from the video playback request a first requested time point and a segment data length of the single-fragment video; downloading video data from the first requested time point of the target single-fragment video, and forwarding the downloaded video data to the playback end for real-time playback; and when a data length of the downloaded video data being equal to the segment data length, simultaneously downloading and caching one or more data segments following the data segment corresponding to the first requested time point in the target single-fragment video. On the basis of ensuring smooth playback of the single-fragment video data by the playback end, this disclosure accelerates data downloading and caching of the single-fragment video.
